Solution

The correct options are
A Water is decomposed into hydroxyl and hydrogen ions.
B Light energy is converted into chemical energy.
C Oxygen is given out during this process.
Light dependent reaction is also called as light reaction as it occurs in the presence of sunlight in the grana of the chloroplast.
During light reaction, water is broken down into hydroxyl and hydrogen ions and oxygen is given out. In this phase, light energy is converted into chemical energy which is utilised during the light independent reaction.
